Newly Adopted Claim Construction Overcomes Anticipation & Obviousness Rejections
| May 2, 2018
Wonderland NurseryGoods Co., Ltd. v. Baby Trend, Inc., Denny Tsai, Betty Tsai
April 19, 2018
Before Moore, Prost & Newman. Opinion by Moore.
Summary:
The CAFC reversed the Board’s findings of anticipation and obviousness due to an erroneous claim construction. The newly adopted claim construction by the CAFC is consistent with the specification and prosecution history. Further, the CAFC held that the references of record did not anticipate nor render obvious the claims in light of the newly adopted claim construction.
要旨:
米国連邦巡回控訴裁判所(cafc)は、米国特許庁審判部のクレーム解釈が誤りであることを認め、誤ったクレーム解釈に基づく新規性ならびに自明性の判断を覆した。cafcが示したクレーム解釈は、当該米国特許の明細書ならびにプロセキューションヒストリに鑑みたものである。再発行特許(リイシュー)の手続き内で行なわれた補正が、権利範囲を拡張するためのものであったのか、あるいは、引例を回避するためのものであったのかが争点となった。
Details:
U.S. Reissued Patent43,919 (hereinafter ‘919) is directed towards “an easy to assemble baby crib in which a fabric member is positioned on a bed frame structure.” Id. at 2. The terms at issue are “a fabric member” and “an enclosure member”.
In two inter partes review (IPR) proceedings, the Board determined that “a fabric member” means “one or more pieces of fabric” and “an enclosure member” means “one or more members.” Id. at 2. In light of this construction, the Board held that the claims of the ‘919 Patent were anticipated U.S. Patent No. 6,004,182 (“Pasin”) and Australian Patent No. 715,883 (“Bidwell”) and would have been rendered obvious by Pasin in view of U.S. Patent No. 7,063,096 (“Stoeckler”), Bidwell in view of Stoeckler; U.S. Patent No. 3,924,280 (“Vaiano”) in view of Pasin and the combination of Vaiano, Pasin and Stoeckler. It is noted that the Board “stated that Vaiano taught ‘a single, continuous member’.” Id. at 3. Wonderland appealed.
“In IPR proceedings, the Board gives claims their broadest reasonable interpretation consistent with the specification. PPC Broadband, Inc. v. Corning Optical Commc’ns RF, LLC, 815 F.3d 747, 751 (Fed. Cir. 2016).” Id. at 3. The CAFC reversed the Board and held that the Board erred in its constructions of the terms “a fabric member” and “an enclosure member.”
Although the use of the singular articles “a” and “an” often means “one or more” when the transitional phrase “comprising” is used, Convolve, Inc. v. Compaq Computer Corp., 812 F.3d 1313, 1321 (Fed. Cir. 2016), in this instance, the Board’s construction is inconsistent with the use of the terms in the claims.
The ordinary language of the claims indicates that a single fabric or enclosure member is capable of separating the interior of the claimed crib from the exterior.
Id. at 3. The CAFC held that “a fabric member” and “an enclosure member” “must be unitary structures able to ‘delineate’ or ‘surround []’ an ‘enclosed space’.” Id. at 4. The CAFC held that their claim construction is consistent with the specification, including preferred embodiments, examples and the drawings. “Although we must be careful not to read limitations from the specification into the claims, the specification’s use of the claim terms in a manner consistent with their use in the claims further supports our conclusion.” (emphasis added) Id. at 4. The CAFC dismissed the Board and Baby Trend’s reliance upon prosecution history to support the original claim construction by noting that claim amendments by Wonderland “were part of a series of changes emphasizing that the ‘fabric/enclosure member surrounds an enclosed space adapted for receiving a baby therein’ J.A. 1853, made in response to the examiner’s citation to a prior art reference directed to chairs.” Id. at 4-5. The CAFC held that the proper construction of “a fabric member’ and ‘an enclosure member’ refer to unitary elements that separate the interior of the claimed crib from the exterior.” Id. at 5.
In light of the newly adopted claim construction, the CAFC held that the “Board’s alternative finding that the claims are unpatentable under the construction we now adopt is not supported by substantial evidence.” Id. at 5. Baby Trend, relying upon the Board’s finding that Vaiano taught a single, continuous member, argued that Vaiano disclosed the claimed features under the newly adopted claim construction. The CAFC disagreed, noting that the citation of Vaiano cited by the Board did not support their position, and that Vaiano merely discloses a netting feature. The CAFC concluded that the disclosure of Vaiano “does not indicate that the netting is a single, continuous member.” Id. at 5. Further, the CAFC dismissed Baby Trend’s argument that Vaiano depicts a continuous, single member because the lines of netting are aligned in one corner, as illustrated in Figure 1, by noting that the lines in the other corners were not aligned. “While it is possible that a single, continuous piece could be used in Vaiano, that is not the question before us. Instead, we ask whether Vaiano discloses a single, continuous piece. Substantial evidence does not support the Board’s finding that it does.” Id. at 6.
Id. at 5. Lastly, the CAFC dismissed Baby Trend’s argument that the Board inherently relied upon their expert testimony regarding the disclosure of Vaiano by noting that merely finding an argument persuasive does not deem said evidence adopted. “When the Board intends to rely on extrinsic evidence, it does so expressly. A single citation to 10 pages in a petition does not incorporate by reference every piece of evidence referenced therein. Similarly, Baby Trend may not rely on statements made by Administrative Patent Judges at the oral hearing that were not included in the Board’s written decisions.” Id. at 6.
Takeaway:
Review claim construction to ensure it is consistent with the specification. The disclosed use of a claim term can affect claim construction.
Carefully review each reference to determine if the Examiner’s understanding is accurate.
